Inventor Qwaoia WW Patented June 6, 1950 I present invention relates to novel and im- I proved-adjusting means for seat cushions such. as

are used, in seat .constructions in automobiles,

, and the like, and has reference, in particular, to ,hand regulated adjusting means which is introduced,and: interposed between the stationary baseor underframe and cushion, and, which serves to vertically raise and lower the cushion in a ma ner to; place itat a correct level for safe and reliable driving.

'sible operating means for. the jack, and an cushion and to allow same to be raised or lowered togmeet-the requirements of the occupant.

Certain ,makes of present-day automobiles,

particularly coaches and other styles having twin or double seats at the front, are often such that the driver is compelled to sit on a level which makes it impossible to obtain a clear and ready view of the complete radiator and fenders. Experience has shown that this low-level principle is not only objectionable but is highly unsafe. Consequently, many accidents can be traced to this low-seating arrangement. It follows, therefore, that my aim is to provide means which can be installed in already marketed cars and which, in an equivalent form, might well be installed in cars at the time of manufacture, the attainable results being such as to promote safe and reliable driving requirements.

Other objects, features and advantages of the invention will become more readily apparent from the following description and the accompanying illustrative drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views Figure 1 represents a fragmentary portion of the front seat construction of an automobile with the cushion on one of the seats equipped with my improved adjusting and hoisting means.

Figure 2 is a view in section and elevation, the same being taken approximately on the plane of the line 2-2 of Figure 1, looking in the direction of the arrows.

Figure 3 is a top plan view of the invention per se, detached from the rest of the structure.

Figure 4 is a side view of the structure seen in Figure 3 with a portion shown in section.

In Figure 2, where the general assembly is best 5 i lshowmthe backrest'of the seat structure is denotedatiA, the seating cushion is indicated at g B, and the relatively stationary base frame for 'saidcushion is'denoted at C. -Thefioor of the 1 More specifical1y,1the invention pertains to a" suitablelifting and lowering jack, readily accesautomobile is indicatedat D. p p

shown in Figures 3 an, the lifting and lowering means is in the form of a jack,'this being an ordinary lifting jack. and denoted genf erally by the numeral 8. The base of the jack is "denotediat 9 and the standard at ID. The adjustable lifting and lowering head is denoted at H. The numeral l2 designates an operating rod which is. operativelyconnected with the mech- [a'nisnrof the jackand is provided on its outer "end with a hand-Wheel or equivalent part I3 The aforementioned seat cushion adapter unit is denoted, generally speaking, by the numeral [4 and in the form of the invention seen in Figures l to 4, inclusive, comprises a frame made up of strap metal arms l5 and I6 welded or otherwise connected together, as at H, in crossed form. Thus, the frame is of general cruciform design in top plan and the extreme outer ends of the respective arms are upturned to provide retaining and assembling lugs I8. These lugs engage the marginal coacting portions of the cushion B. Welded to the underside of the cruciform frame is a cup H) which fits down over the head of the jack, as shown in Figure 4. The jack, incidentally, is of either mechanical, pneumatic, or hydraulic form and is, of course, not claimed here except in the broad sense, that is, as a lifting jack. The essence of the invention, therefore, comprises a jack which is seated on the base C, which is provided with manual operating means accessible through the front of said base, just below the driver of the car, said jack being provided with the adapter means I4 which serves to accommodate the cushion. It follows, therefore, that the invention has to do with a lifting and lowering jack having accessible operating means, said jack interposed between the cushion and its base and being provided with an adapter device for coaction with the cushion. Hence, the cushion can be vertically raised to take a predetermined position such as is required by the particular user for safe vision and driving.

In the modification seen in Figures 5 and 6, the construction is basically the same and the jack is denoted by the numeral 2|), the same having a head 2| fitting in a cup 22 on the central underside of a, single bar or strap member 23. Here again the strap member is provided at its outer ends with upturned hooks or lugs 24 for coaction 5 with the cushion. In both forms of the invention, the cup-equipped device is, generally speaking, an adapter with an arm or arms, said arm or arms having hooks or lugs'engageable with the cushiorhrm 3.,
